1. The selection box expands symmetrically about the middle of the image. One should be able to move any side so as to pick any part of the image.

After editing a page the changes are not lost but also not shown if you change pages, so you have to close and re-open the document.

I got this error message when compiling jpeg lib with ndk-build:

I tried sugestions described on stackoverflow[1], and replacing () with [] worked for me.

I have openSUSE 12.3,

Dialog should show

• ocr confidence (happy or unhappy fairy image)
• in case of bad confidence option to open help dialog for tips
• option to copy text to clipboard
• option to export as pdf
• option for text to speech

Hallo, f und i werden permanent zu dem fi-Symbol. Könnte man das Symbol aufgrund der Seltenheit entfernen?

Allow user to configure Export options:

1. pdf yes/no
2. raw text yes/no
3. include image in pdf yes/no

or better yet. try out the new android studio

in the crop image screen the user must be able to rotate the image also by using the rotate gesture.
This feature must be made discoverable by an overlay or pop up dialog.

Since the text flows differently on small phone screens than on printed paper the app should detect words that are separated by hyphens and remove the hyphen.

Can you please put to the preferences option to select location of tesseract language data?

navigating the app should be easier. I want to remove the start screen activity and replace it with the navigation drawer pattern.
The navigation list shall include

• whats new
• tips
• about
• get involved

remove language data from apk. let user download it manually after installation or use extension file.

since upgrading to latest version of tesseract the quality of the paragraph detection has decreased. find out why

1. do tiled color cluster analysis to find regions that have
  * only 2 different clusters of colors
  * one cluster is then the text color (it should be the smaller cluster, probably very dark, or very light)
  * the other cluster is  the background color on which the text is printed
  * it is possible to have more than one text background color for the whole document
      * build a list of background colors
2.  now  some assumptions can be made
  * tiles which have only one cluster of color which is in the list of  text background colors can be thresholded away since they are probably only naked paper
  * all tiles that have more than two clusters of color must be preserved as image regions
3.  what is left are regions that qualify as text regions but in reality might also be  lines, drawings, dirt specks etc. 
      * lines could be filtered out by connected component analysis or other means. 
      * Dirt specs and other noise might also be filtered away after ocr

Problems:
what is the text color for step 1?

It should be easier to copy the text to the clipboard

After adding a page to a document it shows "loading image" forever and never shows the new page, you have to press back 2 times and re-open the document.

-Per document settings:
-_auto rotate (90, 180, -90)
-_auto select scan type (single, multiple, no-ocr)
-optionally open to last page by default.
-option to remove a failed scan/page from a document
-option to auto process (with less aggressive or no cropping) a directory of images

In the crop image screen the user must be able to invert the image

At the moment it is not possible to move your app to sdcard (version 1.1.4). It would be great if you enable it.

Can you please fix "building-from-command-line" to current git code? I found out that procedure described is not complete[1]:

1. After 'git clone' I need to run:
   cd textfairy
   git submodule init
   git submodule update
2. After "get a coffee" there should be "cd .."
3. There is no directory 'NineOldAndroids'. So the command the relevant code should not mentioned there + it have to be removed from project.properties[2].
4. Maybe it would be good to mention that user should use target installed on computer instead of "17", otherwise they will get error: "Error: Target id '17' is not valid. Use 'android list targets' to get the target ids." when they run "android update lib-project -t 17 -p ActionBarSherlock/actionbarsherlock"
5. I need to run "android update project -t android-14 --path ." instead of "android update project --path ."
6. There is no ant-debug (on opensuse 12.3. 64 bit ;-). I need to run:
   ant
   ant release

Unfortunatelly "ant release" finished with error:
[aapt] Generating resource IDs...

1. The image displayed for choosing the part of the image to extract text from was about the size of a postage stamp on my ten-inch tablet screen. It should be scaled to fit the screen, perhaps limited to 100%.

Allow user to make multiple fotos one after the other. The OCR process should then be done in a background service.

Allerdings gibt es ein Problem beim verändern des Tessdata Verzeichnises. Ich habe ein Samsung GT-S7710 (Xcover 2) mit Android 4.1.2. Seltsamerweise nennt Samsung in diesem Gerät den internen Speicher sdcard0 und die SD-Karte extSdCard. Das führt dazu das viele Apps ihre Daten im internen Speicher ablegen und dieser sehr schnell voll ist. Also habe ich den gesamten Textfee Ordner nach extSdCard verschoben und in der App den Pfad extSdCard/Textfee/Tessdata angegeben. Die App funktioniert jetzt auch mit allen bereits heruntergeladenen Sprachen allerdings bricht der Download weiterer Sprachen immer ab. Beim antippen der Sprachdatei erscheint der wandernde Ladebalken sowie das Downloadsymbold in der Statusleiste. Dann verschwindet das Downloadsymbol und die Wlan Aktivität stoppt. Als Workaround bin ich gerade dabei die Sprachpakete nach und nach auf die Sd-Karte zu kopieren.

Let other apps call the text fairy via the Android intent system
